TL;DR: The metabarcoding approach presented here is non-invasive, more efficient, more cost-effective and more sensitive than the traditional survey methods and has the potential to serve as an alternative tool for biodiversity monitoring that revolutionizes natural resource management and ecological studies of fish communities on larger spatial and temporal scales.

TL;DR: An eDNA method to estimate the biomass of common carp using laboratory and field experiments and demonstrates that the distribution of carp eDNA concentration was explained by water temperature, suggesting that biomass data estimated from e DNA concentration reflects the potential distribution ofCommon carp in the natural environment.

TL;DR: It is suggested that eDNA analysis is a useful tool to estimate fish abundance/biomass as well as their spatial distribution in rivers.

TL;DR: Positive relationship between fish size and eDNA release rate support the possibility of biomass rather than density estimation using eDNA techniques, and suggests that quantitative eDNA data should be corrected using a degradation curve attained in the target field.

TL;DR: In this paper, the authors evaluated the accuracy of qPCR and ddPCR to estimate species abundance and biomass by using eDNA in mesocosm experiments involving different numbers of common carp.
